Detailed Description


Wilson Combat has reengineered the SIG-SAUER P365/P365XL grip frame to optimize its practical shooting and concealed carry potential.  These all-new molded polymer grip modules will enhance your grip and improve recoil control.  Our significant improvements in shape, texture, and overall ergonomics will give your P365 the superb feel of an expertly hand sculpted custom gun with a simple grip change. These six new models cover standard and XL P365 frames, with or without a manual safety in black and tan color.

Our fresh look at the P365 grip module incorporates the suggestions of tactical trainers, champion shooters, and firearms experts into the final product that has a look that is unmistakably “Wilson”.  We believe it is the most practical, comfortable, and stylish P365 grip available and the ideal choice for concealed carry and defensive handgun use.

These are non-serialized, newly manufactured grip modules and are not serial numbered firearms.

Best upgrade for a P365
This grip frame is a much better fit for my hand than the original it came with from Sig. The little bit bigger palm swell makes a big difference in how well it fits my hand. I also prefer the grip texturing on the Wilson Combat grip. If you're interested, you can watch a video on my first impressions and installing the grip on my pistol on my YouTube channel:
Wow Awesome grip module
Feels more natural to hold, fits my medium hands perfectly , great texture and the high grip with the extended beaver tail genhances the gun control and recoil. Well worth the upgrade.
Second 365 grip
Bought my second P365 WC grip. I also have 2 more for my Sig M18 and M17. Really prefer the WC grips over the stock Sig grips.
I stand corrected I was shipped the wrong equipment grip is still incredible and works great with the Streamlight TLR6 for P365. My apologies for the previous comment!
Great Grip But
I love the grip but it will not work with Streamlight TLR- 6. Kind of frustrating.
Great combination
I wanted the 10rd size but the P365x grip felt better, especially the beavertail area. I added a Hogue to the P365 and that helped. When I found this I thought it would be perfect with the 1911 beavertail and reshaped grip. It is. Feels much better. I now get my pinky on the 10rd extended mag. As small and light as possible. Very pleased. Put me on the list for nice matching extended 10rd and 12rd magazine bases.
Great grip
Very happy with this purchase. For hand size I wear a large glove. I never liked how the 365xl felt, especially where my middle finger hit the trigger guard. This grip was a noticeable improvement. After reading stories about trying to reuse mag release im glad the grip came with one to make installation easy.
What I've been waiting for
Where the stock grips always felt too small between trigger to backstrap for my hands, this grip makes me feel like I can really clamp down on my P365 and offers more space for confident support hand placement. The stippling in the indentations on the sides feels like "home" for the support palm. The backstrap texture is a little too aggressive for my tastes, where the sig stock texture was one of the things i liked about it. But that's not a huge issue once I limit handling this thing to range time. Right now my strong palm is kind of sore because I've been feeling the WC grip out for hours at this point. I haven't had a chance to take this to the range, but pretty much immediately I have a confidence in my grip on this gun where I struggled with it previously. I hope Wilson Combat will consider making some floor plates for the 12 round mags that fall in line with the new grip and perhaps line up with the backstrap and feel similar to their XL grip with the flush mag.
Not as good as I had hoped.
I wanted to like this standard 365 grip, but the fit by the magazine is not good. Because the base is wider than the magazine, there are two sharp points to dig into your hands. Additionally the 12 round magazines don’t fit correctly. At this point, I’m wishing I had selected the large size grip where I probably wouldn’t have these issues.
Definite Upgrade
Some nice surprises. It has a palm swell which makes it fit my hand better. And it doesn't have that cheap feeling flex around the mag well that the original Sig grip has. I have yet to shoot or carry it, but so far it feels less abrasive against the skin in a AIWB holster than the original grip. I hope they make some 12 round magazine grip extensions to match. There is a bit of a transition to grip extension on the factory 12 round mags because of the thicker palm swells, but it doesn't really bother me in the hand.
Its perfect.
Flawless fit and finish. No marks from mold. Better quality than original Sig module which always have a dimple at the front edge of the slide bottom. Color is also perfect. Bought the weights but I don't think they are necessary. One of the complaints I had with my 365 is the fit to my hand. This solves it - slightly wider in all the right places. Plastic quality and the feel is perfect. The ONLY thing I wish they included was a standard picatinny rail instead of the Sig rail.
Need Tan Color
Like the upgrade, however prefer the tan color for the manual 365 module…will wait until it’s an option.
